<P>PROBLEM TO BE SOLVED: To provide a substation monitoring system capable of more stably supplying power in substation facilities by detecting abnormality of a wiring connection part in addition to abnormality of various electric apparatuses in the substation facilities. <P>SOLUTION: A substation monitoring system for detecting abnormality of various electric apparatuses 11 and abnormality of a wiring connection part in substation facilities 10 comprises: an ultrasonic wave detector 13 which detects an ultrasonic wave amount generated at the various electric apparatuses 11 and the wiring connection part, and outputs the amount as a signal; a relay monitoring device 14 relaying the signal from the ultrasonic wave detector 13; and a centralized monitoring device 15 which is connected to the relay monitoring device 14 by a company LAN 17, and monitors the abnormality of the various electric apparatuses 11 and the abnormality of the wiring connection part in real time on the basis of the signal from the relay monitoring device 14. The centralized monitoring device 15 determines the abnormality of the various electric apparatuses 11 and the abnormality of the wiring connection part, when the ultrasonic wave amount detected by the ultrasonic wave detector 13 exceeds a preset upper limit value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
